| Popis: | Background Impaired brain glucose metabolism appears to be a potential pathogenic feature of mild cognitive impairment (MCI). This study examined the potential for increasing circulating ketone bodies through medium chain triglyceride (MCT) supplementation, as a means to beneficially modulate brain homeostasis in subjects with MCI. Methods Six participants with MCI were enrolled in a randomized placebo-controlled trial. Participants received 56 g/day of either medium chain triglycerides (MCTs) or placebo for 24 weeks. Serum β-hydroxybutyrate concentrations, apolipoprotein-E4 status, and cognitive assessments were carried out. Due to the small number of participants only the raw scores were examined. Results Intake of MCT oil increased serum ketone bodies and improved memory, while intake of placebo did not show improvement in any of the cognitive measures tested. Conclusions Consumption of 56 g/day of MCTs for 24 weeks increases serum ketone concentrations and appears to be a candidate for larger randomized control trials in the future that quantify the modulation of cognitive function through supplementation with ketone precursors, in patients with MCI. Highlights • Subjects included those with a diagnosis of mild cognitive disorder. • Subjects were supplemented with 56 g of medium chain triglycerides (MCTs). • MCT supplementation increased postprandial serum betahydroxybutyrate concentration. • MCT supplementation improved memory. • Ketones likely counteract the effects of impaired cerebral energy metabolism. |
